Ukraine setting up 'invincibility centres' says Zelenskiy

STORY: Russian attacks have knocked out power for long periods for up to 10 million consumers at a time. Ukraine's national power grid operator said on Tuesday the damage had been colossal.

"If massive Russian strikes happen again and it's clear power will not be restored for hours, the 'invincibility centres' will go into action with all key services," Zelenskiy said.
